[All] I think Young K stands out the most on stage. I heard the KSPO DOME concert was really great.

Young K DAY6's world tour 'Forever Young' held at the KSPO DOME in Seoul Olympic Park in May 2025. The concerts were held six times in total from May 9th to 11th and 16th to 18th, and Young K stood on stage as DAY6's bassist and main vocalist. This concert marked the last of DAY6's 9-month world tour, entering KSPO DOME for the first time in 10 years since their debut, on the 360-degree revolving stage.

The concerts drew 16,000 audiences for each show, with a total of 96,000 fans, which is the largest audience mobilized by a single artist at KSPO DOME. The stage was set up in the center circle to reflect the band's characteristics, and it slowly rotated so that the members could be seen up close from any seat. Young K perfectly performed DAY6's representative songs such as 'Congratulations', 'You Were Beautiful', 'Letting Go', and 'I Loved You', as well as new songs, going back and forth between bass and vocals.

At the end of the concert, Young K told his fandom My Day, “As an artist, one of the things I always worry about is what if people want us less someday. But at every concert, I feel like My Day is telling us, ‘Stop worrying and just do music. ’” He continued, “When we get older, the scale of our concerts may get smaller, but if I can still meet My Day then, that’s enough for me. Thank you for letting me continue singing,” and he seemed to choke up.

On this stage, Young K once again confirmed Day6’s musical growth, deep bond with fans, and promise to continue making music in the future. He shared with fans the experiences and emotions he had accumulated while touring the world with the members for 9 months, and at the end of the concert, all the members shed tears and said, “This was such a precious and challenging tour.” Young K’s heartfelt message and energy on stage left a deep impression not only on the fans who were there, but also on many who heard news of the concert.
